The Complete Guide to TI-89 Calculator Games

The TI-89 and TI-89 Titanium are legendary not just for their Computer Algebra System (CAS), but for their robust gaming capabilities. Powered by the Motorola 68000 processor, these calculators can run everything from simple text-based puzzles to complex grayscale 3D shooters.

Types of TI-89 Games

• BASIC Games: Written in TI's proprietary language. These are easy to read and edit on the calculator but are generally slower. Examples include simple RPGs and puzzle games.
• Assembly (68k) Games: Written in low-level machine code. These are incredibly fast and allow for high-speed graphics, grayscale effects, and complex physics. These require kernels like DoorsOS or PreOS on older firmware, or can run natively on newer ones.
• Flash Apps (.89k): These are installed in the "Archive" memory. They appear in the Flash Apps menu and don't take up precious RAM, making them ideal for massive games.

How to Install Games on your TI-89

To get started with gaming, you will need the TI Connect software and a SilverLink or standard USB-to-mini-USB cable (for Titanium models).

1. Download the game: Look for files ending in .89z (program) or .89k (app).
2. Connect: Plug your TI-89 into your PC or Mac.
3. Transfer: Drag and drop the files into the TI Connect software.
4. Unarchive: If the game is in the "Archive" (indicated by a '*' next to the name), you must use the Unarchive command to move it to RAM before execution, unless it's a Flash App.

Example Storage Scenario

If you have a standard TI-89 Titanium, your storage management might look like this:

Game Title	Type	Approx. Size
Phoenix (Shmup)	Assembly	42 KB
Mario (Platformer)	Assembly	65 KB
Tetris	BASIC	4 KB

In this setup, you would be using roughly 111 KB of your 188 KB available RAM, leaving plenty of room for math variables and graph history.

Critical Tips for TI-89 Gamers

Always back up your calculator before installing new Assembly games. Because Assembly runs at the kernel level, a bug in a game can cause a "Address Error" or "Illegal Instruction," forcing a complete calculator reset which wipes all unsaved variables.
